Mercury's movements give scientists peek inside the planet
The first measurements of Mercury's movements from a spacecraft orbiting the planet reveal new insights about the makeup of the solar system's innermost world and its interactions with other planetary bodies, found a new study recently accepted in Geophysical Research Letters.
New research calls for rethinking of New Zealand's Alpine Fault
The major fault line of New Zealand's Alpine Fault, which runs almost the entire length of the South Island, has been assumed to be a near vertical crack. However, a new study of seismic data in Geochemistry, Geophysics, Geosystems has revealed the fault line becomes flatter at depth.

A deadly parasite that causes Chagas disease is widespread in a common Texas insect, according to a new study by University of Texas at El Paso (UTEP) researchers. The finding suggests that the risk of Texans contracting the disease may be higher than previously thought.
The parasite Trypanosoma cruzi (T. cruzi), which causes Chagas disease can be transmitted to humans by blood-sucking insects known as "assassin bugs" or "kissing bugs." Unlike mosquitoes that transmit malaria through the bite, kissing bugs drop feces on the subject while filling up with blood. The feces, ...
A low resting heart rate in late adolescence was associated with increased risk for violent criminality in men later in life, according to an article published online by JAMA Psychiatry.
Low resting heart rate is related to antisocial behavior in children and adolescents. Low resting heart rate (RHR) has been viewed either as an indicator of a chronically low level of psychological arousal, which may lead some people to seek stimulating experiences, or as a marker of weakened responses to aversive and stressful stimuli, which can lead to fearless behavior and risk taking. ...
Among patients 70 years or older who underwent elective surgery, major complications contributed significantly to a prolonged length of hospital stay while delirium contributed significantly to several adverse outcomes, including length of stay and hospital readmission, according to a study published online by JAMA Surgery.
Major postoperative complications and delirium contribute independently to adverse outcomes and high resource use in patients who undergo major surgery; however, their interrelationship has not been well examined. Understanding the risks of adverse ...
A follow-up of nearly 60,000 women who received a synthetic vaginal mesh sling for the treatment of stress urinary incontinence finds the risk is low for needing a second surgery for mesh removal or revision (about 1 in 30 women ten years after surgery), according to a study published online by JAMA Surgery.
Female stress urinary incontinence (SUI) is a common condition that is often treated with surgery when conservative management options are unsuccessful. An estimated 1 in 7 women will undergo surgery for SUI during their lifetime. Synthetic mesh slings are the most ...
BOSTON -- Researchers from the Aging Brain Center at the Institute for Aging Research (IFAR) at Hebrew SeniorLife confirm that delirium is a significant and independent contributing factor to poor postsurgical outcomes in older adults. Findings published in JAMA Surgery suggest that the combination of major postoperative complications and delirium demonstrate a strong combined effect on adverse outcomes in older adults undergoing major surgery.
Of all inpatient operations in the U.S. in 2007, 36% were performed on patients 65 years of age or older, and that number is ...
Capsaicin, the compound responsible for chilis' heat, is used in creams sold to relieve pain, and recent research shows that in high doses, it kills prostate cancer cells. Now researchers are finding clues that help explain how the substance works. Their conclusions suggest that one day it could come in a new, therapeutic form. Their study appears in ACS' The Journal of Physical Chemistry B.
About 10 years ago, researchers reported that capsaicin can kill prostate cancer cells in mice while leaving healthy cells unharmed. But translating that dose to humans would require ...
An isolated, iron-rich bay in the heart of East Africa is offering scientists a rare glimpse back into Earth's primitive marine environment, and supports theories that tiny microbes created some of the world's largest ore deposits billions of years ago.
According to University of British Columbia (UBC) research published this week in Scientific Reports, 30 per cent of the microbes in the Democratic Republic of the Congo's Kabuno Bay grow by a type of photosynthesis that oxidizes (rusts) iron rather than converting water into oxygen like plants and algae.
"Kabuno Bay ...
Smoking has been shown to have drastic consequences for lifespan and disease progression, and it has been suggested that cigarette exposure may impact the risk of death and disease via its acceleration of the aging process. Not all smokers experience early mortality, however, and a small proportion manage to survive to extreme ages.
Using long-lived smokers as their phenotype, the authors of a study published today in The Journals of Gerontology, Series A: Biological Sciences & Medical Sciences identified a network of SNPs (a DNA sequence variation occurring commonly ...
WASHINGTON - The percentage of poor children who received federal disability benefits for at least one of 10 major mental disorders increased from 1.88 percent in 2004 to 2.09 percent in 2013, and such growth is consistent with and proportionate to trends in the prevalence of diagnosed mental disorders among children in the general U.S. population, says a new report of the National Academies of Sciences, Engineering, and Medicine. The increase also is not unexpected. This is because a sizeable number of low-income children with disabling mental disorders do not receive ...
BOSTON -- Racial and ethnic inequalities in medical care are widely documented in literature. However, variations in Americans' experiences with healthcare, specifically regarding physician-patient communication and shared decision-making about treatment plans, are not well understood. A new study from Boston Medical Center, which suggests that a patient's race/ethnicity may influence the amount and type of information they receive from physicians regarding treatment recommendations, is published online in advance of print in the journal Patient Education and Counseling.
"It's ...
